"Left the comfort of your parents home to make it on your own and then have an agency say hey we'll foster you like your parents did is welcoming."

The message is welcoming. But will other people get that after one look at this ad?
I think it's a bit too complicated. And I have to point out, although the idea is cool and the composition is attractive, the execution is rather poor. It doesn't look like the womb until I read the head, and the whole thing is too obvious that it's a (bad) Photoshop work. Why did the background blend into his shirt near the shoulder area. I have never seen picture of a fetus where the womb blend into it before, so I doubt it's intentional.
